固定球阀
产品型号:Q47F
产品口径:DN50-DN800
产品压力:PN1.6-PN10.0MPA
产品材质:碳钢 CF8
固定球阀,球体带有固定轴的球阀,称为固定球阀。固定球阀主要用于高压大口径。根据阀座密封圈的安装不同,固定球阀可以有两种结构:球体前密封的阀座,球体后密封的阀座1、结构特点
2、整体结构
如图5所示。具有全通道、紧急密封、防火等特点。
3、全通径
阀门流道孔直径与管和径内径一致,更于管线清扫。
4、阻塞与排泄
阀门处于关闭状态时,上下游侧的阀座使流体阻断,阀体中腔的积治物可以排泄,排泄装置如下机能:
① 事前可检查阀座是否泄漏损伤;
②减少介质更换对阀门的污染;
③ 在工作压力下,阀门处于全开或全关状态时,可更换阀杆部填料函。(如图5所示排泄装置是排污塞)
5、自动泄压
阀门中腔停滞的介质由于温度升高,而出现异常升高时,阀座或阀体上安装的安全阀可以自动泄压。
6、防火结构
采用双重密封,当发生火灾时,非金属阀座烧损后,介质将球体压紧在阀体上的金属密封面阻止介质大量漏出,符合API607规定。
7、紧急密封
阀座及阀杆密封件出现损伤而引起泄漏时,通过注脂阀注入密封脂可以起瞬时应急密封作用。
8、阀杆加长
阀杆加长适用于地下安装及低温介质用,加长尺寸,根据需要确定。操作方式有手动、气动、电动、气液联动、液动等。
